New England Patriots safety Patrick Chung has been ruled out of the clash with rivals the Philadelphia Eagles, the NFL Super Bowl champions announced.
Chung will miss Sunday's showdown in Philadelphia due to two injuries (heel and chest), after the 32-year-old had initially been listed as questionable.
A three-time Super Bowl champion, Chung – who spent a year with the Eagles in 2013 – was limited all week in practice.
Rookie running back Damien Harris will also miss the road game against the Eagles (5-4) because of a hamstring problem.
The Patriots (8-1) are looking to bounce back from a loss to the Baltimore Ravens prior to their bye week.
